Activation function impact on rainfall prediction: comparative insights across ML and DL architectures
This study systematically compares a wide variety of activation functions (Sigmoid, ReLU, Tanh, Swish, Leaky ReLU, and ELU) across deep learning architectures (LSTM, BiLSTM, and Transformer) and traditional ML models (Logistic Regression, SVM, KNN) to assess their impact on rainfall prediction accuracy, convergence, and generalization. It highlights the superior performance of BiLSTM with ReLU/Leaky ReLU and Transformer with ELU/ReLU/Swish, achieving up to 99% accuracy.
Executive Impact
Activation functions critically impact deep learning model performance in rainfall prediction. Our analysis shows that BiLSTM with ReLU or Leaky ReLU, and Transformer models with ELU, ReLU, or Swish, consistently outperform traditional ML models and other activation functions, achieving up to 99% accuracy. This leads to more accurate, stable, and generalizable weather prediction systems, reducing risks associated with floods and droughts. Implementing these optimized models can significantly enhance decision-making in agriculture, water resource management, and disaster planning, leading to substantial cost savings and improved societal resilience.

Advanced Deep Learning for Rainfall Prediction
Our analysis focuses on sophisticated deep learning architectures: Long Short-Term Memory (LSTM), Bidirectional LSTM (BiLSTM), and Transformers. These models excel at capturing complex temporal dependencies inherent in meteorological data.
The study systematically evaluates the impact of various activation functions—Sigmoid, ReLU, Tanh, Swish, Leaky ReLU, and ELU—on these architectures. Notably, BiLSTM with ReLU/Leaky ReLU and Transformer with ELU/ReLU/Swish achieved up to 99% accuracy, demonstrating superior performance in rainfall prediction.
Traditional Machine Learning Baselines
To benchmark the performance of deep learning models, we employed several traditional machine learning classifiers: Logistic Regression (LR), Support Vector Machines (SVM), and K-Nearest Neighbor (KNN).
These models, while serving as robust baselines, displayed an intermediate predictive accuracy, with average accuracies of approximately 87%. This highlights the significant advantage of deep learning architectures in handling the nonlinear and complex interactions of meteorological factors for precise daily rainfall forecasting.
